Msc C0nD,`of the a'foresaidcityfof New vYork, ltave f invented ti-new and useful Improvement in Steam-Generators, of nhich the following is e..ful l, clear, and exact description, reference being had to the accompanying dravving forming part of this specification, and in which-- Figure l'representafa sectional elevation ci' steam-generator constructed accordingto our improvefn'ent;and i, l i

-This, our improvement, has reference in its leading or ma'infeature of action to a steam-generator of 'vertors detached, with its supporting-bracket 'tical character, and4 in which aspray'orthin current of water is converted into steam as it passes dovm aud overheating-surfaces 'or plates; 4and our invention consists iii a novel combination of Viiue-enlargen'len'ts within the generator, containing .draught-'deiiectors, in combination with lower-Water courses` or dividing-plates to the generstcrlprovided '5r-ith suitable outlets' or escapes, and'whcrehy the water is converted linto steam in its prog- -ress down Vthrough the generator. Our inventiori'nlso consists'in the combination of u sprinkleror feed-Water distributer, with a generator constructed-s above described. Likewise our-invention consists in' an arrangement of e coldair spacoebetweena super-heaterand the fire-box arch of the generator. Italso consists in s novel construction of feerl-'atcrhatcr in anautomatic p'ressureregulntor for controlling the supply of' steam to tho super-beater. l y

. Referring tol the accompanying drawing, A represents the iroplaco ofV the generator, and a the grate-bars thereof; B is the 'ash-pi't,'undf0 the door for feeding'y in the iucl. This portion ofthe generator may be formed I of an outer metallic box opensc, D, with re-hricli` sides and arch or roof E, having an upper or central'drnughtoutlet,.'b, and-side draught-passage c. Mounted upon this boar or case is a steam super-,heating lvessel or cha'mv ber', 4F', through' which the draught is established by au opening or pipe, d, into and. through the generator proper, when it fis'desired to thus Vpassthe smoke `and gaseous products of combustion, whollyor iu port, inI

f preferenceto allowing their escapo through the s ide'passage c into a main flue, Gr, forming or contracted with' the chimney, and provided at or nearits lbottom with it damper, e.- Between-thc' superheater F end arch E 'l v of' thejireplace is an airpnssnge,f, commuriicatinggrith thc uppernox'v central draught-outlet d','and prn,vldedwith oneorllnore cold-airinlts-g, having .valves or vdempers for opening,` shutting ofi, or regulating the'sl'zpplyA of external air to the passagef. 'Mounted-'again upon tllesuperheatcr is the steam-generator proper, cousistl ingofan outer shell or case, ,-H, `to which h "is the top or roof, and inner. cylinder or case I, leavinga nteamV space, z',..around it, and extending from the roof or.top 'It'l to near the baise of thc outer shell H, and formed with s slopin'g tar-invertedconical-shaped hottom, j, having a central opening, k, in it, surrounding the draughtppe d, ofasiz'e to. form an annular spaccarcund the latter. i p

Arranged or connected with and supported by the inner cylinder I', at a suitable'distance apart, one above ,the 'other,"are any desirednumbcr of slopingor inverted conical-shaped dividingplates or deectors K', similar to'thebottom, j, and Aextending from the si'desof the inne'r cylinder, witha ccntralOpcning, @through them, of

a sizewhich will leave'an annular space around pipes or 'vertical ,branches m, t'ha t -forrn continuation, as it i were,ot"v the draught-pipe d', and which serve to connect vessels or chambers, L 4arranged in succession above the dividing-plates or deiiectors K. I' These vesselsor chambers L arc of aclose'cliaracter, being formed ofa top-plate, u, and inverted' conieal-sbaped bottom-plate, V@and are of a size which will leaves free spaceabove, below, and around them; end establish communication between the Vopenings 1 ofthe decctors K. Within each 4of' these chambers or vessels L, is a due-dividing disk or di'aught-deector, M, supported in an insulated manner by a bracket or stand, p, and preferably of a configuration correspon'dingto the interior of' either vessel L, but;

'Smaller than it, vso as to leave a free -iiue-space.under, over, and aroundcach disk.

Seated on the t'op,'z,. of the shan or case I I isa feeldwater heater, N, prdridcd internally with encor more of the vessels L, hereinbefore described, with draugbtdeflector AM, lower dividing-plate K, and pipes or branches m, the latter connecting thc. vessel L, or,l inn. case of a duplication or series ofrthe'm, one above the other, vesselsrL with the corresponding. vessels in the generating-'cylinder below, and with an upper branchfp'ipe, g, leadwater from this feed-water heater'.

`ngto the main flue orsmoke-pipe G, and provided with a damper, r. Udsan overfiew-pipe,fo r ,the surplus To work the generator, a quick or direct. draught maybe got en first starting the fire, by opening .the i dnmper'e, and closing or partly closing the damper r, which dempers mayaftcrwnrds be regulated at pleasure,

as circumstances in the' working require; but when it is dcsirethto concentrate heat in the generator, the lower .dampere should be closed, and theupper one, zu', opened. Water toevorkthe generator is iirst pumped, forced, 'or let into the-heater N, and the supply to the latter kept' up as re'quired 'by a pipe, P, provided 4with a perforated distributor or sprinkler, s, arrnged over the one or upper vessel L in the heater, by which means 'a uiorcl equable division of thejpcomingwater, and better diffusion of it over and around the heating-vessel L, is or are 'i secured, thereby d'imirl-isl1ing`tliecooling effect of itlupon the water lying at the bottomlcf the heater N, which is kept -Warl'n or hot by the heat of the steam inthe cylinder or case I below, and by the-passage of -the prodacts of combustirrthrough it, -v L v The several-'chambers orvessels L, with -theirdeflectors M, and connecting-branches m, it will be seen, operate to givel an extended heating-surfaceor action, as the smokeand heated gases wcrktlieir'way upwards, as indicated by the arrows ar, through said vessels L, which, by the trialnsvei'seA position that they occupy within the case I, end by the aid-ofthe deilectors M, exercise a general spreading or diffusing action, so that on water being drawn vfrom the'heater N by a pipe, Q, .and forced, by pump or otherwise, through a pipe, R,Vand sprinkler t, into the upper portion of' the cylinder I, it, in coursing 4its way-over, around, and beneath the vessels L, arranged' in said cylinder, and over thedividing-plates K 'therein,'@.s indicated by the rrows'c, will, by the extended plate-heating surface to which it'is exposed, and comparatively slow or long detour given it, be, or for l'the most part, converted into steam priordto reachingv the outlet k.

Of course thisv introduction of .the water Vin a spray form, or in any other' way'that'will cause it to circa- 4late over the upperyvessel or vessels L and plates K of the cylinder I, in a thin sheet or successionof sheets,v

' largely contributes tothis result, and'wherebywater, oratzlleast any largebody of it, never need remain in the generator, ,and steam may be produced-in a mostrapid manner, and that either constantly' or at intervals, as

the demand requires,.hy` simplyestablishing, for the period, as steam is required, the feed of weiter through the pipeR; When it is not desired to generate steam, aud'thefeed of water is shutoff, thenA 4the'upper flue-damper v r should be clcse'd, andthe lcwerpne, e, opened.

It will be' obvious that' various changes ma'ybe'umde in the construction or shape of theparts withoutv departure from thegprinoiple of the invention, such as th'efshape of 'the cylinder I, dividingplates K, end-'Vesl' sels Inzwith-thei'r detlectors M,' but it is important vthat the draught 'should be established around vor beneath and over the latter, and that i the water-course .shonldbeo'vcr` the'vessels in which.` they are located.

Toclearr the generator, it may be provided with a central 'vertical shaft, S, worked from the exterior, and

providedwith arrows or scrapers u, arranged s o thaton rotating the shaft, they will sweep the interior surfaces cf the vessels L, and exterior faces o'f, the deflectors M or either, the one arm orscraper -wlnichworks under either deflector, preferably being curved to sweep inwards, while th'e next arm orscraper above' it is shaped to their centre.

pressure ofthe steam 'from the generator lifts the valve d?, nndfthis supplies the .aupenhehter with ndditiohal steam, but, on the super-heater containing `abimdance ofn steam at the required pressure, 4the "alved is kept,V

=closed against any further supply from the generator'by the pressure` of the superbe-ated'stcam'passing up 4the.
